FASTENING DEVICE.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed September 27, 1907. Serial No. 394,809.

To all whom it may concern:

Be it known that I, J OHN J. OOoNNELL, of L1ma, Livingston county, NewYork, have invented certain new and useful Improvements in FasteningDevices, of which the following is a specification.

y invention relates to fastening devices designed particularly for usein connection with the side curtains of vehicles of all kinds, and theobject of the invention is to improve the device shown and described inLetters Patent 0f the United States issued to me April 16, 1907, No.850,599.

y invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a front view illustrating the application of my invention to theside curtains of a vehicle. Fig. 2 is an edge view of the same. Fig. 3is a sectional view illustrating the manner of separating the parts ofthe fastening device. Fig. 4 is a sectional view through the socketportion of the device. Fig. 5 is a similar view with the shank removedfrom the socket.

In the drawing, 2 represents a portion of the buggy top or quarter, and3 a portion of one of the side curtains. 4 is a plate secured by screws5 to the top 2 and having a lug 6 formed thereon and projectingoutwardly in a plane substantially at right angles to the plane of thesupporting has a cup shaped socket 7 formed therein and a slot 8terminating in a circular hole 9 extending vertically through the bottomof the socket 7. The other member of the fastening device consists of aplate 10 that is secured to the curtain 3 and provided with an upwardlyextending shank 11 which is substantially circular in cross section andterminates in a head 12 that is formedto fit within the socket 7 andrest snugly on the bottom thereof. The shankand head are so formed thatvertical movement of the shank is permitted in the hole 9 but outwardmovement in a horizontal plane which would tend to separate thefastening devices, is prevented.

When it is desired to separate one member of the fastening device fromthe other the plate 10 is swung outwardly, the head 12 forming a pivottherefor and the shank 11 passing freely through the slot 8 until. thehead is entirely disengaged from the socket.

This movement is indicated in Fig. 3. In my plate 4. This lug 6 formerpatent it was necessary to rotate the shank a quarter turn before suchmovement or rotation could take place. I have found, however, that inmany instances the fastening device will be sufiiciently secure if theparts are separable merely by swinging the lower section outwardly andupwardly until its shank is withdrawn from the slot 8. Such movement ofthe parts cannot take place accidentally and the separation'can beeffected a little more uickly than where it is necessary to partia lyrotate the shank before disengaging it from its socket.

To revent the shank from becoming accidentally disengaged from thesocket I prefer to provide a groove or recess 13 extending around theinner surface or face of the socket and adapted to receive a spring 14which has ends 15 fitting within recesses 16 in position to be engaged bthe shank and compressed suificiently to a low the withdrawal of theshank from the socket. Normally, however, the throat or passage betweenthe ends of the spring will be too narrow to allow the passage of theshank until the spring ends are put under compression.

This device is designed for use as a fastener on buggy and automobiletops and the addition of the sprin herein described renders the deviceparticu arly eflicient for use on horse blankets and for other purposeswhere a fastener that cannot become accidentally unfastened is required.

I claim as my invention:

1. A fastening device comprising a plate having an outwardly projectinglug rovided with a socket having its axis para lel with said plate andsaid socket tapering from one end towards the other end, and said lughaving a hole extending through it from said latter end of the socketand its wall having a longitudinal slot extending from end to endthereof, a second plate having a shank terminating in a head that isadapted to enter the larger end of said socket but is too large to passentirely therethrough, and said shank being adapted to swing outwardlyand upwardly through said slot on said head as a pivot to separate oneplate from the other, and said shank having a sufficient longitudinalmovement in said socket to permit said outward and upward swingingmovement.

2. A fastening device comprising a plate having an outwardlyprojectinilug provided with a vertical socket, said soc et having an theopening on one side extending through wall of said lug, a second platehaving a shank that is adapted to enter said opening and fit Within saidsocket and a spring arranged Within said socket and having spring endsthat project into said passage and into the path of said shank,substantially as described.

-3. A fastening device comprising a plate having an outwardly projectinglug provided with a socket having an annular groove in its inner surfaceand an opening extending through the Wall of said lug, and the Walls ofsaid lug having recesses on each side of said l l l l 1 opening, aspring adapted to it within the groove in said socket and having curvedends to enter said recesses, and a second plate having a shank to passthrough said opening and engage and compress said spring ends, and saidshank having also a head to it within said socket.

In Witness whereof, I have hereunto set my hand this 5th day ofSeptember 1007.
